mongodb复制集环境下搭建单向复制

[soberass]

需求：已有一个2.4.6版本MONGODB复制集，A,B,C三台机器，一主一丛一仲裁，想让这组复制集作为主库，再搭建一个从库，意思就是从复制角度上，复制集整个或其中一个节点是主节点，新增加D机器作为从节点，我试验了，在无认证环境下可以跑通。但加了认证后，从节点连不上主节点，谁有这方面的经验，谢谢

副本集加auth 复制之间用keyfile认证

谢谢你的恢复 有复制集和复制的配置文件样例没

[soberass]

我试了 复制集没问题 但 加了KEY后 复制不通 复制集配置： dbpath=/data/mongodb/t1 logpath=/data/mongodb/t1/master.log pidfilepath=/data/mongodb/t1/master.pid directoryperdb=true logappend=true port=27017 oplogSize=100 fork=true replSet=test quiet=true master=true keyFile=/data/mongodb/t1/mongo_key auth = true 复制配置： dbpath=/data/mongodb/t4 logpath=/data/mongodb/t4/master.log pidfilepath=/data/mongodb/t4/master.pid directoryperdb=true logappend=true port=27020 oplogSize=100 fork=true quiet=true slave = true auth=true keyFile=/data/mongodb/t4/mongo_key source = 10.20.0.12:27017 复制这个无论加不加auth都不通，如果不加认证 ，圈没问题

谢谢你的额回复，但我的需求不是搭建RS，我的需求是已有RS，在此基础上再增加一个单向复制，也就是说RS作为整体是主 ，新增加一个复制从库

我的从库其实就是认证通不过，错误日志如下： mongod(_ZN5mongo11msgassertedEiPKc+0x9b) [0xd9f55b] mongod(_ZN5mongo10ReplSource14sync_pullOpLogERi+0x4880) [0xba0fa0] mongod(_ZN5mongo10ReplSource4syncERi+0x2d3) [0xba14b3] mongod(_ZN5mongo9_replMainERSt6vectorIN5boost10shared_ptrINS_10ReplSourceEEESaIS4_EERi+0xea) [0xba3f8a] mongod(_ZN5mongo8replMainEv+0xc1) [0xba4691] mongod(_ZN5mongo15replSlaveThreadEv+0x4c) [0xba4b1c] mongod() [0xe26609] /lib64/libpthread.so.0(+0x7aa1) [0x7f7a5ed12aa1] /lib64/libc.so.6(clone+0x6d) [0x7f7a5e0b7bcd] Tue Oct 24 01:17:13.227 [replslave] repl: AssertionException trying to slave off of a non-master 如果是无认证模式下，不会有问题，有认证下，怎么试抖不通过
